Definitions

  • the invention relates to a ventilation system for the rooms of buildings, in which in the parapet area under a window a ventilation device with at least one supply air blower, which is in flow connection with an air intake opening on the outside and an air inlet opening on the inside, and a heat exchanger is arranged under the ventilation device.
  • a ventilation system intended for the rooms of buildings which comprises a ventilation device arranged in the parapet area under a window, each with a fan for supplying fresh air and for removing room air.
  • a radiator is arranged under the ventilation unit, which can be operated in a conventional manner as a room heater, but can also be acted upon with a cooling medium if necessary and which is supplied with fresh air when fresh air is supplied to the room.
  • the radiator which can optionally be operated as a radiator or also as a cooling element, is coated with the air supplied to the room, it can be warmed up or cooled down if necessary.
  • the object of the present invention is to further develop and improve the previously known ventilation system, in particular with regard to its efficiency.
  • the air inlet opening is directed towards the heat exchanger and the ventilation device is assigned a veneer on the inside of the room, which extends beyond the heat exchanger and at least partially covers it towards the room, and a flow path for one Forms air flow guided over the heat exchanger, which can be shut off in its upper area against the outflow from the heat exchanger as a result of convection of rising warm air.
  • the invention is therefore that for the fresh air supplied from the ventilation unit and exiting inside the room, a forced control is created such that the fresh air exiting from the ventilation unit flows over the heat exchanger and only then enters the room to be ventilated close to the floor.
  • the heat exchanger is operated as a radiator or as a cooling element, the air supplied is effectively heated or cooled.
  • an operating mode is also possible in the ventilation system according to the invention in such a way that, without prejudice to a supply air flow conducted via the heat exchanger, a convection current rises, which enters the room through the outlet openings on the above-mentioned flow path.
  • This mode of operation is a mixed operation in which the supply air is heated and discharged from the heat exchanger down into the room becomes, while at the same time an increasing convection current enters the room through openings on the top of the blind.
  • the air inlet opening of the ventilation device opens out over the part of the heat exchanger near the parapet and extends approximately over half its depth.
  • the ventilation unit When the ventilation unit is switched off and the heat exchanger is operated as a radiator, it acts in a conventional manner in that a convection current rises and enters the room through the outlet openings on the top of the blind.
  • the purpose of the new ventilation system is that this system can optionally be operated with cooling and heating of the fresh air supplied, without the need for an additional fan.
  • the ventilation system according to the invention is therefore simple and inexpensive in construction.
  • a particularly simple construction of the ventilation system succeeds if the cover extends to a top cover of the ventilation device, for example to a window sill covering the ventilation device.
  • the veneer from a ventilation grille is one forms an internal chamber on the inside of a flow channel with the air inlet opening directed downwards, and is formed from a covering which extends downward from the ventilation grille and extends approximately to the lower edge of the heat exchanger installed at a distance from the room floor.
  • Such an attachment chamber can be part of the housing of the ventilation device or also attached to the device. In the latter case, it is easy to retrofit a conventional ventilation system into an air conditioning system.
  • a flap that can be pivoted between an open position and a closed position can serve as a shut-off element, which can shut off the attachment chamber on the underside, for example.
  • the flow path formed by the veneer is provided on the top with an adjustable lamella grille which, in the open position, allows a convection flow rising from the heat exchanger to flow into the room, but on the other hand completely completes the flow path to the room formed by the veneer is able to complete.
  • a ventilation device 14 each with a supply air and exhaust air section 15, 16, is accommodated in a recess 11 of a parapet 12 under a window 13 which is only indicated.
  • the supply air section 15 comprises a blower, not shown, which is in flow connection with an air intake opening, also not shown, on the outside of the room and an air inlet opening 18 opening out on the inside of the room.
  • the interior air inlet opening 18 of the ventilation device 14 is directed downward and below the ventilation device projecting into the room there is a heat exchanger 20 in the form of a radiator, which is arranged at a distance from the floor 21 of a room and towards which the air inlet opening 18 of the ventilation device pointing downward is directed .
  • the ventilation device 10 is covered on the top by a window sill 22 which projects inside the room above the ventilation device.
  • a veneer 24 is assigned to the ventilation unit 10 on the inside of the room, which consists of a ventilation grille 25 on the underside that reaches the window sill 22 and a cladding 26 that extends downwards from the ventilation grille 25 on the underside and extends approximately to the lower edge of the heat exchanger 20.
  • the ventilation grille 25 is spaced from the interior end of the ventilation device 14 arranged so that a chamber 28 inside the room is formed behind the ventilation device 14, and equipped with adjustable slats 29 between a closed and an open position.
  • the supply air section 15 of the ventilation device 14 is supplied with fresh air drawn in from outside, it exits through the air inlet opening 18 on the underside of the ventilation device 14 and acts on the heat exchanger 20 arranged under the air inlet opening 18, as the arrow 30 indicates. If the heat exchanger 20 is operated as a radiator, the fresh air flow conducted through it is heated and then flows according to arrow 31 under the cladding 26 of the cover 24 and flows into the room.
  • the heat exchanger 20 can also be operated as a cooling element, with the result that fresh air conveyed by the blower to the supply air section 15 of the ventilation device 14 and supplied through the air inlet opening 18 according to arrow 30 is cooled when the heat exchanger 20 is coated.
  • the ventilation device 14 is received in a recess between a window (not shown) and a parapet 12 and is covered on the upper side by a window sill 22, which however only extends approximately to the end of the ventilation device 14 on the room side.
  • a boundary 25 Connected to the upper side between the window sill 22 and the ventilation device 14 is a boundary 25 which projects obliquely downwards into the room and is provided with air passage openings on the upper side, to which a cladding 26 which extends approximately to the lower edge of the heat exchanger 20 is connected.
  • fresh air supplied from the blower of the supply air section 15 of the ventilation device 14 via the air inlet opening 18 hits the parapet close to the parapet Areas of the heat exchanger 20 and then enters the room in the heated state according to arrow 31 under the cladding 26.
  • the fresh air supplied is heated or cooled.
  • room air flowing in under the cladding can rise as a convection current and enter the room through the air passage openings of the sloping cover 25 when the shut-off valve 34 is in the open position.
  • FIG. 3 differs from the above-described embodiments according to FIGS. 1 and 2 only in that the facing 24 extends from an approximately upward extension of the lower edge of the heat exchanger 20 and then connected to the ventilation unit 14 on the upper side there, the upper part of this cladding is equipped with an air guide element 35 and forms an attachment chamber 28 which communicates with the room via a guide grill formed by the slats 29 which can be actuated between a closed and an open position can also be locked if necessary.
  • the front chamber 28 is part of the housing of the ventilation device.
  • the wall of this front chamber pointing towards the room is perforated and provided with a ventilation grille in the form of adjustable lamellae 29 and connect the front chamber to the room to be ventilated or to close it off.
  • the front chamber 28 is again one
  • a flap 34 which can be actuated about a pivot axis between a closed and open position is assigned, by means of which, in the same way as in the embodiment according to FIG.
  • an ascending convection current is released for outflow into the space to be ventilated or the front chamber 28 can be closed, so that then , depending on the operation of the heat exchanger 20 as a heating or cooling body, fresh air supplied from outside is introduced into the room in the heated or cooled state.
